    Hi Paulo. Thanks for the suggestion. I'm not going to number the videos, as I'll be adding videos and I don't want to have to renumber. I put these videos up primarily for my students, in support of my text that I supply them, and it's easy for them to keep the order straight. But I do want to make it easy to follow along. I've created playlists for the major topics, and I've ordered the videos within each playlist. At some point I'll get a website up to help keep these videos organized. Cheers.

    If the people who are under correction take 3% of total population and we randomly select 2 people and the probablity that at least one person is under correction is supposed to equal 0,06 , ( 3× 2% ) And what's Wrong with this statement?
